POS (POSmill) spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of POS spindles and motor spindles — the German builder of CNC machining centres for SMEs, with the POSmill range and HSK 63A spindles reaching up to 18,000 rpm.
POS, a German builder of CNC machining centres for SMEs
TLDR: POS claims nearly half a century of experience in machine tool building, with POSmill CNC machining centres designed for medium-sized businesses, and a range comprising the C800, C1050 and E1100 series as well as the H 500 U, H 800 U and H 1000 U 5 axis gantry centres.
POS, a German manufacturer of CNC milling machines for medium-sized businesses, highlights nearly half a century of experience in machine tool building. Its POSmill range covers several machining centre series: the C800, C1050 and E1100 models, regularly cited by their users, as well as the H 500 U, H 800 U and H 1000 U vertical 5 axis gantry centres.
On user forums, the POSmill H 800 U is valued for its weight of around 20 tonnes — roughly double that of a comparable compact centre — and for the quality of contact with the manufacturer. POS also offers a scalable automation solution compatible with POSmill centres, for workpieces up to 500 × 500 × 500 mm. This is an SME fleet that often runs long batches under automation: the availability of the POS spindle directly governs the output of the cell.
A range of POS HSK 63A spindles, up to 18,000 rpm, on a Meehanite cast iron gantry
TLDR: POSmill H 800 U and H 1000 U centres are built on a ribbed Meehanite cast iron gantry structure — claimed to be up to 60% more rigid and damping than comparable machines — with feed rates up to 60 m/min, and use HSK 63A spindles reaching 18,000 rpm, with a 96-tool magazine.
The POSmill H 800 U and H 1000 U 5 axis centres are built on a gantry design combined with ribbed Meehanite cast iron construction, large rotary axes and oversized drives, which according to the manufacturer provide up to 60% more rigidity and vibration damping than comparable machines. The dual drive on the Y axis, four high-precision Heidenhain scales, and a Heidenhain TNC 640 or Siemens SINUMERIK ONE control complete the design, with travels varying up to 1,000 × 1,200 × 700 mm, table loads up to 2,000 kg and traverse rates up to 60 m/min, for simultaneous 5 axis machining.
On the spindle side, a 2016 POSmill H 800 U is fitted with an HSK 63A taper with a maximum speed of 18,000 rpm, a 96-tool magazine, an 800 mm table and a Heidenhain iTNC 630 control; a 2017 POSmill H 500 U reaches 14,000 rpm with a 60-tool magazine and a 500 mm diameter Kessler rotary table. A 96-tool magazine means as many clamping and unclamping cycles: on these POS spindles, the tool clamping system is a wear point we check systematically, alongside the bearings.
